The race is a mass start event, during which, after several laps of the circuit, the first rider to complete the distance is declared the winner.
At the start, riders will be positioned in the starting line according to their current UCI ranking. The higher position riders will be placed at the front of the group. Should a rider be lapped at any time during the race, the rider must finish that lap and then is removed from the competition by a commissaire via a designated finish lane before the start of the finish straight. The lapped rider will be listed in the results in order of finish plus number of laps down.
The course is an undulating circuit designed to produce an optimum winning time, not a specific distance. Time parameters are listed below (in hours and minutes).

Baseball is a bat-and-ball sport played between two teams of nine players each. The goal is to score runs by hitting a thrown ball with a bat and touching a series of four bases arranged at the corners of a ninety-foot square, or diamond. Players on one team (the batting team) take turns hitting against the pitcher of the other team (the fielding team), which tries to stop them from scoring runs by getting hitters out in any of several ways. A player on the batting team can stop at any of the bases and later advance via a teammate’s hit or other means. The teams switch between batting and fielding whenever the fielding team records three outs. One turn at bat for each team constitutes an inning; nine innings make up a professional game. The team with the most runs at the end of the game wins.
Evolving from older bat-and-ball games, an early form of baseball was being played in England by the mid-eighteenth century. This game and the related rounders were brought by British and Irish immigrants to North America, where the modern version of baseball developed. By the late nineteenth century, baseball was widely recognized as the national sport of the United States. Baseball on the professional, amateur, and youth levels is now popular in North America, parts of Central and South America and the Caribbean, and parts of
. The game is sometimes referred to as hardball, in contrast to the derivative game of softball.
In North America, professional Major League Baseball (MLB) teams are divided into the National League (NL) and American League (AL). Each league has three divisions: East, West, and Central. Every year, the champion of Major League Baseball is determined by playoffs that culminate in the World Series. Four teams make the playoffs from each league: the three regular season division winners,
wild card team. Baseball is the leading team sport in both Japan and Cuba, and the top level of play is similarly split between two leagues: Japan’s Central League and Pacific League; Cuba’s West League and East League. In the National and Central leagues, the pitcher is required to bat, per the traditional rules. In the American, Pacific, and both Cuban leagues, there is a tenth player, a designated hitter, who bats for the pitcher. Each top-level team has a farm system of one or more minor league teams. These teams allow younger players to develop as they gain on-field experience against opponents with similar levels of skill.棒球球棒和球的运动，由两队各有九名队员。我们的目标是通过与蝙蝠和感人的一系列安排在一九零平方英尺的角上的四基地打丢球得分，或钻石。一队的球员（棒球队）轮流打在对方的投手（守备队），试图阻止他们的得分让打者在任何的几种方法。在棒球队的一个球员可以停在任何后来的前进基地通过队友的打击或其他手段。在击球和防守时的防守球队记录三出局的球队开关。每队一次蝙蝠又构成一局；九局构成了一个专业的游戏。游戏结束时，最负责球队获胜。从旧棒球球棒和球游戏，早期的形式是在英格兰踢了第十八世纪中叶。这个游戏和相关的圆场棒球是由英国和爱尔兰移民带到美国北部，那里的现代版的棒球了。第十九世纪后期，棒球被普遍认为是美国全国性的体育运动。棒球在专业，业余爱好者，和青年的水平是现在流行在美国北部，中部和南部的美国和加勒比海地区，以及东亚地区。游戏有时被称为强硬，相反的垒球衍生游戏。在北美国，职业棒球大联盟（MLB）小组分为国家联盟（NL）和美国联盟（Al）。每个联盟有三个分支：东，西，和中央。每年，美国职业棒球大联盟的冠军的季后赛，最终在世界大赛中确定。四队来自各个联赛季后赛：常规赛三个分区冠军，加上onewild卡队。棒球在日本和古巴的领导团队运动，和发挥最高水平的两个联赛同样分裂：日本中央联盟和太平洋联盟；古巴西部联盟东部联盟。在国家和中央联盟的投手，所需的蝙蝠，按传统规则。在美国，太平洋，和古巴队，有十分之一名球员，指定打击，他们的投手蝙蝠。每个顶级球队有一个或多个小联盟球队的农场系统。这些团队让年轻的球员成为他们获得对领域的经验，对类似的技能水平的对手。
Baseball is a sport played between two teams usually of nine players each. It is a bat-and-ball game in which a pitcher throws (pitches) a hard, fist-sized, leather-covered ball toward a batter on the opposing team. The batter attempts to hit the baseball with a tapered cylindrical bat, made of wood (as required in professional baseball) or a variety of other materials (as allowed in many nonprofessional games). A team scores runs only when batting, by advancing its players–primarily via hits, walks, and the opposition team’s fielding errors–counterclockwise past a series of three markers called bases and touching home plate arranged at the corners of a ninety-foot square, or “diamond.” The game, played without time restriction, is structured around nine segments called innings. In each inning, both teams are given the opportunity to bat and score runs; a team’s half-inning ends when three outs are recorded against that team.
